Seiko Prospex Fieldmaster – Automatic

Mint condition Seiko Prospex Fieldmaster. It comes with the original box and papers and was originally purchased from Cencibel Watches in June 2015 so just 1 year old when taken into stock. It comes with the original tan leather strap, and comes with secondary “lumpy” bracelet as shown in the pictures. It is a sought after Japan only market. The addition of the Prospex specification does indeed make the piece wear larger than most. The case itself is already huge, measuring at a diameter of 48mm (50.5mm with crown) and a thickness of 13.7mm, this piece is definitely a piece that wants to be noticed. Furthermore, the piece is also on the heavy end of the wristwatch spectrum as with all Prospex pieces, weighing in at 126 grams. All these specifications are basically made to make it so that this is a piece to be worn on the field. In fact, if you have been in the Seiko Watch circle long enough, the original Fieldmaster or more commonly known as the “Contra Watch” was actually a piece designed to be worn by Nicaraguan rebels. Movement wise, the “Field Tuna” is powered by a robust 6R15 caliber. A movement, which you find in the majority of the automatic pieces from the PROSPEX line. The 6R15 caliber is actually a movement that’s just a step below the top-notch 8L35 movement and an upgraded version of the 7S26. Essentially, it’s another undecorated piece of engineering marvel from Seiko. It’s one of the few movements from the Seiko mechanical movements that offer hacking and hand-winding mechanism, by simply adding a separate pinion on an existing movement to enable the winding without needing to recreate a new movement from scratch. It’s actually a redesign of the 7S26 caliber, but the wonders of adding a hacking capability and hand winding makes it a cut above the rest of the mechanical watches from Seiko. Some technical specifications of the Seiko Fieldmaster SBDC011 are shown below:

Movement: 6R15 Caliber
Drive System: Self-winding mechanical with manual winding
Water Resistant: 20 bar
Jewels: 23
Weight: 126 g
Dimensions: 48mm diameter x 13.7mm thickness

The Seiko Fieldmaster or the “Field Tuna” is without a doubt, a unique piece that shows its elegance from its no nonsense design. Even with the similarities with the Marinemasters, the Fieldmaster deserves a spotlight of its own. With current pricing of approximately 94,500 Yen (950 Euros) including taxes, the piece is considered to be a watch with good value. An affordable luxury tool-watch as some would say, and a very good one at that. Another gem from the Japanese-only made pieces that collectors around the world would want to grab a hold of. And just to make things more interesting, I am leaving you with a photo of the “Field Tuna” beside its limited edition hard-coated sibling.
